/* This file contains a collection of macros that can be used to reduce
 * repetitive code. As new macros are written to support of refactoring,
 * they should be placed here.
 */

/* NAME is used as part of the GMPy function name. It usually uses an upper-
 *      case first character.
 * FUNC is the component of the actual name used by MPFR and MPC.
 *
 * Note: the following macro can release the GIL.
 * GMPY_MPFR_MPC_UNIOP_EXWT(NAME, FUNC) creates the following functions:
 *     GMPy_RealWithType_NAME(x, xtype, context)
 *     GMPy_ComplexWithType_NAME(x, xtype, context)
 *     GMPy_Number_NAME(x, context)
 *     GMPy_Context_NAME(self, other)
 *     - called with METH_O
 *
 * Note: the following macro is only used for is_xxx tests so it does 
 *       not release the GIL.
 * GMPY_MPFR_MPC_UNIOP_TEMPLATEWT(NAME, FUNC) creates the following functions:
 *     GMPy_Number_NAME(x, context)
 *     - assumes GMPy_RealWithType_NAME & GMPy_ComplexWithType_NAME exist
 *     GMPy_Context_NAME(self, other)
 *     - called with METH_O
 *
 * GMPY_MPFR_MPC_TRIOP_EX(NAME, FUNC) creates the following functions:
 *     GMPy_Real_NAME(x, y, Z, context)
 *     GMPy_Complex_NAME(x, y, Z, context)
 *     GMPy_Number_NAME(x, y, Z, context)
 *     - assumes GMPy_Integer_NAME & GMPy_Rational_NAME also exist
 *     GMPy_Context_NAME(self, args)
 *     - called with METH_VARARGS
 *
 * GMPY_MPFR_MPC_UNIOP_TEMPLATE(NAME, FUNC) creates the following functions:

 *     GMPy_Context_NAME(self, other)
